VEVOR PTO Shaft, 1-3/8″ 6-Spline, Series 4, 43″-61″
The Series 4 VEVOR PTO shaft is forged to handle heavy-duty agricultural tasks. Features a solid 20CrMnTi carburized steel universal joint and a Q345 steel tube inside a protective shield. This construction emphasizes durability for a range of implements and tractors, with a 1-3/8″ diameter and 6-spline tractor end paired to a round implement end. It’s designed to deliver robust power transfer and dependable performance in field conditions.
Length is adjustable: compressed to 43″ and extendable to 61″. It supports differing speeds on each side of the drive line and lists torque figures suitable for common 540 and 1000 rpm operations. While not featuring a slip clutch, it remains a solid choice where slip protection isn’t required.
VEVOR PTO Shaft, 1-3/8″ 6-Spline, Series 4, 31.5″-41″
This Series 4 unit includes a slip clutch and a solid 20CrMnTi universal joint, with a Q345 steel tube. The 1-3/8″ diameter and 6-spline ends align with a broad array of bush hogs, finish mowers, or rotary cutters. The telescoping design provides a compact storage length of 31.5″ and extended reach of 41″, enabling flexibility for various implements and tractors.
Power ratings reflect 540 rpm and 1000 rpm operating windows. A slip clutch helps protect equipment from sudden loads, reducing the risk of damage during tough cutting tasks.
VEVOR PTO Shaft, 1-3/8″ 6-Spline, Series 5, 43″-57″
Series 5 adds a slip clutch to the robust Series 4 foundation. It features a solid 20CrMnTi universal joint and a Q345 steel tube. The ends are 1-3/8″ with 6 splines, ensuring broad compatibility with compatible tractors and implements. Compressed length of 43″ and extended length of 57″ give users adjustable reach for varying equipment setups.
Torque figures at 540 rpm and 1000 rpm indicate strong performance, particularly at higher PTO speeds. The slip clutch provides added protection against overloads in demanding mowing or shredding applications.
VEVOR PTO Shaft, 1-3/8″ 6-Spline, Series 4, 39″-55″
This 39″-55″ Series 4 shaft maintains the standard 1-3/8″ diameter with 6-spline ends on both sides, and a robust 20CrMnTi universal joint inside a Q345 steel tube. The telescoping tube design grants a compact compressed length of 39″ and an extended length of 55″. It is suitable for a range of bush hogs, finish mowers, and rotary cutters, providing steady torque and reliable engagement.
Two ends—one tractor end with 6 splines and a round implement end—offer straightforward compatibility. The unit’s torque characteristics suit mid-range cutting tasks, with strength to handle typical field conditions.
SCITOO Yellow 37″-59″ PTO Shaft, Series 4
The SCITOO Series 4 PTO shaft features a telescoping design with 1-3/8″ 6-spline tractor end and 1-3/8″ 6-spline implement end. The compressed length is 37″ and extends to 59″, offering flexibility for various mowing and cutting setups. It uses a solid 20CrMnTi carburized steel universal joint within a Q345 steel tube, ensuring durability under heavy use.
Torque specifications cover 540 rpm and 1000 rpm ranges. The design supports dual-speed operation, enabling efficient power transfer to bush hogs, finish mowers, or rotary cutters without needing frequent adjustments.
ECCPP PTO Shaft, 37″-59″ Series 4
The ECCPP 37″-59″ Series 4 PTO shaft is designed with 6-spline tractor and 6-spline implement ends, both 1-3/8″ in diameter, aligning with a wide array of tractors and equipment. It features a solid 20CrMnTi universal joint and a Q345 steel tube inside a shield for durability. A compressed length of 37″ extends to 59″, making it adaptable to different implement-to-tractor configurations.
It provides 540 rpm and 1000 rpm torque ranges, with robust performance designed for bush hogs and finish mowers. The absence of a slip clutch means protection against overload relies on other drivetrain safeguards or careful operation.
Buying Guide: Key Considerations For Choosing A PTO Drive Shaft
- Length range and adjustability: Select a model whose compressed and extended lengths fit your tractor-implement setup. Telescoping tubes help accommodate different mounting distances.
- End fittings: Most common are 1-3/8″ diameter with 6 splines on tractor and implement ends. Ensure end types match your specific tractor and attachment to ensure optimal coupling.
- Slip clutch presence: A slip clutch provides overload protection, reducing gear and joint wear during heavy cuts. If your operation is high-torque or involves large cutters, a slip clutch is advantageous.
- Joint and tube material: Look for a carburized steel universal joint (e.g., 20CrMnTi) and a protective steel tube (often Q345) for durability and resistance to bending or impact.
- Torque and horsepower ratings: Verify that the PTO shaft’s torque at 540 rpm and 1000 rpm aligns with your equipment’s needs, ensuring efficient power transfer without overstressing components.
- Durability features: CE certification, shield integrity, and overall build quality influence longevity in field conditions and exposure to debris and weather.
- Compatibility and availability: Many brands provide broad compatibility across Bush Hog, finish mower, and rotary cutter lineups. Confirm fitment with your exact tractor model and implement type.
- Maintenance and replacement parts: Consider common wear points (universal joints, slip clutch discs) and the ease of sourcing replacement parts if needed in the future.
In evaluating options, users should balance length flexibility, end compatibility, and overload protection against cost and availability. For users operating heavier mowing tasks or variable terrain, models with slip clutches tend to offer longer equipment life and smoother operation, while standard Series 4 shafts are well-suited for steady, moderate workloads with simpler maintenance needs.
